Congrats on the 6+ score and a new image in your top rated pics row. Its always nice to see shots fall off the other end.
First off let me say that you have great colors. The yellows and green are vibrant yet still real and not over the top. I also really like the textures on the tips of the grass. Offers a nice little bit of extra somethign to the shot. I think you did real well with the vignetting effect - offers good focus on the weed. And you rcomposition is well done too. Nicely off centered - uses the rule of thirds concept well.
A couple of minor issues from me. Maybe a bit heavy on the noise reduction on the weed head. You seemed to have lost some detail from it. Also a little more fine burning on the head to really separate more of the petals, especially on the top part could have allowed it more visible detail.
A nice overall image and your vote curve really reflects that. No real low votes but not many too high either. You have an in general well executed and pleasing image. Had your compostion packed a bit more WOW power you would have scored higher, but without totally reshooting your image I dont think there is anything major that you could have done in post process to achieve that. In the end - nice work, good score and a really good placement in the FS. Keep up the good work!
Need to sharpen the blade on that lawnmower! :D Nice photo overall. The dandelion head seems like it could be sharper (or less noise reduction used). Good luck in the challenge.
Now that's some colour! The detail of the cut rass ends is great. I think the flower needs to come over just a touch to the right - its a little too close to the edge of the photo.
